MULTIPLE-REGORD-PLAYING PHONOGRAPH.

Application filed. September 13, 1923. Serial No. 662,32'3.

This invention relates to phonographs and the general object of the invention is to produce a machine of simple construction which is capable of playing a plurality of records in succession by automatically removing the record being played and substituting a new record for it; also to provide a machine of this type with a magazine for holding the records which are to be played, and to provide automatic means for enabling the magazine to cooperate with the platen which supports the record being played, so as to facilitate the operation of the. automatic mechanism of the machine in effecting the return of the played'record to the magazine and in substituting another record taken from the magazine.

As a machine of this type including a magazine for the records might be used without having the magazine completely filled with records, one of the objects of my invention is to enablethe machine to continue to operate automatically in case a record happens to be absent from its place in the magazine.

A further object of the invention is to provide means to enable the operator of the instrument to stop the playing of any record at will before being completely played, and to construct the auton'ia-tic mechanism in such a way'th at when the playing of a record is suddenlystopped as suggested, the mach ne will immediately operate automatically t remove the record on the platen and substitute another record for it.

A further obj ect'of the invention is to provide simple means for cont-rolling the machiue, and also to provide simple means for efl'ectiug the return of the magazine to its normal position afterthe machine has operated to play all the records.

A further object of the invention is to provide simple means for preventing the returning movement of the magazine from occurring unless the parts of the machine are in proper position to permit such a movement of the magazine.

Further objects of the invention will appear hereinafter.

The invention consists in the novel parts and combination of parts to be described hereinafter. allot which contribute to produce an eflicient multiple record playing phonograph.

A preferred embodiment of the invention is described in the following specification while the broad scope of the invention is pointed out in the appended claims.

Before proceeding to a detailed description of the machine it will facilitate the disclosure to state that the invention involves the use of a rotary platen for holding the record which is being played and includes automatic mechanism for changing the rec 0rd. In order to accomplish this a stack of records is provided, and the mechanism operates to take a record from the stack or a magazine and place it on the platen after having first removed the record which has just been played. In the normal operation of the machine, after a record has been played, the needle is automatically lifted from I the record and the needle arm is automatically returned to its starting position, where; upon the record on the platen is removed trom 1t and the new or substituted record placed on the platen; as soon as this operation takes place the machine operates automatlcally to set the needle in contact will the new record. Any suitable means may be provided for holding the records and enabling them to cooperate with the recordchanging mechanism. however, the machine as described embodies a magazine which carries the records in separate pocle ets, and in the automatic operation of the machine the magazine is advanced by a step by step movement so as to bring the dillerent taken from it by the automatic mechanism fand placed on the platen.

The machine also includes a hand operated member, for example, a lever, which whenv operated immediately stops the playing of any record which happens to be on the platen and brings into operation the regular automatic mechanism which immediately operates to effect the change of the record as though the machine had completed the playing of the record then on the platen.

uitable means isprovided to enable this same hand-operated member to have an extra movement, the function of which is to elifect the return of the magazine'to its normal position, but the 'n'iechanism is so constructed that this extra movement of the lever cannot occur unless the mechanism is held so that all its parts will clear the magazine; this prevents any possibility of the movement of the magazine jamming any or the parts of the mechanism; and I provide automatic means for looking or latching the mechanism in the proper position to permit the movement of the magazine when such a move ment is desired.

I shall now proceed to a more detailed description of the mechanism. The machine comprises a cabinet or casing l which may be of box form as shown in Figures 1 and 2 and provided with double doors 2, and double doors 3, the former of which render the magazine of the machine accessible from the exterior, and the latter of which cover the outer end of the horn or sound duct 4 of the instrument, see Figure 3.

In the upper portion of the interior of the cabinet, a horizontal frame plate 5 is provided, see Figure 8, which supports a rotatable platen 6, which preferably continuously driven, for which purpose the platen is supported on a tubular spindle 7, the lower portion oiwhich carries a gear wheel 8 driven by another gear wheel J which meshes with it. This gear wheel 9 is carried on a vertical shaft 10 supported in the frame 11 of the instrument and con-- tinuously driven through beveled gears 12, one of which is carried on a horizontal shaft 13 driven by a belt from a motor 14;. This motor is preferably a small electric motor, but if desired a spring motor may be used.

Near one edge oi the platen, see Figure 8, a vertical partition wall 15 is provided. the lower edge of which is disposed above the level oi the platen 6 so to form an opening or gap 16 through which the records may he slid out onto theupper face of the platen. The records are received in the space above the platen and beneath a guide plate 17,

which is cut away so as to form a gap or opening 18, see Figure l. lhis gap or opening 18 is provided to permit operation oi? the eedle arm 19 and needle 20 carried thereby. The needle 20 is supported adjacent to a sound box 21 of ordinary construetiim carried on the outer portion 19 oi the arm, which connects with the body the arm by a pivot joint 22 of any common construction, which will permit the needle to be let down onto the record on the platen.

The needle arm 19 rotates on a vertical axis, that is to say, it is swiveled on a you tical axis on a base 23 supported on the horizontal frame plate 5.

The mechanism is preferably constructed so that as soon as the playing of the record is ended, the movement out the needle arm at the end of its travel activates or actuates the automatic :meehanism which then performs the cycle of operations necessary to eff ct the changing of t 1e record, leaving the mechanism again in the same relation which it had when the pla ing of the record commenced. in order to accomplish this, I prefor to employ a counter shaft 2% which is normally held in a stationary position by a stop device 25, see Figure 5. This step de vice includes a slide 26 guided on the upper face of the frame plate 5 by means of screws 27 running in a slot 28, and the outer end of this slide connected by a connecting rod 29 with a rigid arm 30 which extends radially from the needle arm, see Figure -l. The outer end of this stop or slide 26 nor-- mally is disposed in the path of a small arm 81 which is secured by a set screw to the counter shaft, When the playing of a record is completed the arm 30 withdraws the stop 26 and permits one rotation of the shaft 24; that is to say, before the shaft 2% can make more than one revolution the stop 26 is pro-- jected back into the path of the arm 31.

' a short oi the coui'iter shatt it" 2d performs the inside-u of lifting the ieedle oil of the record. and any other it V. c tion wluch is necessary to prepare the platen to have the played record removed from it. As usually ruc'ted every platen has a center pin which is received in an opening in the record. In order to adapt my n1achine to properly center the records and to enable it to play records usually constructcd, I provide the platen with a longitudinally movable sliding pin 32;

In order to lift the needle oi" the record, I provide a guide or guide 1 33, Figure 8, one end of which is pivotally supported on the wall 15, and the o her end of which has a pin-andslot connection wits avertically sliding post .Fl l, which is guided to slide through the traine plate 0. The sound box 21 of the instrument is provided with a horizontal finger which projects out over the upper cd of the guide 2- 3, its movement being limited by two steps 36 and Y7, which. are formed on the uppercdgre of this hat. The first movement the shaft 24; o iera to engage the teeth ot a uutilated (carried on shaft 24) with the teeth pinion, 13. The countershatt is then driven and immediately withdraws the sliding; pin

32 and moves up the post whereupon the guide bar 33 engaging); the finger hits the needle oil the record. it raised position by auautomatic latch to h (lC-SCi'ilDfll hereinafter. This moveu'ien; o the post and sliding; pin 12 1y he accomplished by means of a can]. 38 which ongra es ariu extending; ilp from a reel: shatt said rock shatft carrying a lever, one arm 4-1 of which ha. apiu-z'uid-slot connection with the lower end it the west 3st,. and the other aru'i i2 is formed into a yeke with a pin-and-slot connection with a swivel head at?) onthe lower end of the sl dine 1n 32, which rotates with the plat spring; i iwhich attached (0 the arm 4C1,

The gap 16 between the nu canine and the platen is provided with a s idi 1g gate 4: see Figure 8, which is iiorina iy open.

In order to remove the record on the platen, I provide ejector means preferably. in the term of a curved ejecto' arm 50, see Fi 'ure l, which is secured rigidly to a (l '6 W vcrtual ejector shaft 51, see Figures 4 and This ejector shat; is plOVldQCl with a id arm. 59; to which is attached a connectin rod 53, one end of which has an adjust ahle pin-and slot connection 5% with an actuating lever 55, said lever being mounted to reel; on a fulcrum pin 56 and having two forks forming; a yoke 5'7 which cooperates with a czun carried on the itE Ol'tEEEflt ld counter shett 2 (see l? 6). l Vheii the counter eased and makes its shait it it i ii puts the mechanism thro igrh the cycle 0 movements necessary change the record, the sh it 24: rotates in a right-hand direction, as indicated by the arrow in Figure (5.

The thrust har supported on an ad ustahl-e collar in the form of a nut 62 threaded on by a step by step movement record the post 62. hen the ejector arm performs i s swing to the right to eject a record from the platen, the inner end of this slot 61 engages thepost G2 and pushes the needle arm 19 outwardly, that is to say, it rotates it in a left hand dircztion and brings the stop l er substantially against the outer stop 36 on the guide bar 38, see Figures l and 8. The movement of the ejector arm 50 suliicient to move the record completely through the gap 16, Figure and past the position o the grate ll', see his. 8. As the played record advances, the curved injector arm (33, see Figure 9, withdraws from the pocket in the magazine which lies opposite to the platen and swings way over to the right out of the path ot the magazine so as to permit a feeding movement oi the magazine to bring the next record into almoment with the platen. In order to accomplish this the injector arm 63 carried upon a vertical injector shatt 641i, see Figure l, and this shaft is provided with a rigid arm 65, see Figure 6, which is somewhat similar to the arm 52 on the ejector shaft 'lhis arm 65 is engaged by a pin 66 which projects down from a slide bar 67. connected to the arm 52 by a link 68 and mounted to slide in suitable guides 69 and 70. When the slide bar (37 shifts to the right to its full movement, the pin will hold the arm 63 in an extreme position at the right where it will be out of the path of the curved edge Y1 oi the magazine, see Figure 9. With the inje tor arm .63 in this position, the magazine 45 is then automatically moved so that it will descend through the height of one pocket and bring the next pocke into line with the platen. This movement of the magazine is accomplished by guiding it in a vertical direction and partially counter balancing it, and also by controlling an escape ment device connected with the magazine, through the agency-0t the slide bar 67. For this purpose-the magazine is provided with a central tubular shaft 72, see Figure 8, which telescopes over a lixedpost 73 in the bottom of the cabinet, a helical spring 74: beim); provided on the top Oi the post 78 which thrusts against the bottom of the magazine. This JllllQ' is not quitestrong; enough to support the v eight of the magazine and hence when the eseapement referred to above is actuated, it will permit the. magazineto descend. As suggested, I provide an escapement device 75, see Figure 6, which cooperates with a horizontal shaft 76 carrying a. pinion 7? which meshes with a rack 78 w is c n'neeted with the magazine so that the rack .i'noves when the magazine moves. For

convenience this rack may be formed dictly on th 1, de oi tl etabular shaft 72, see r 8. The escapement device comses a double pawl 79, see Figure 7, co sisting of two oppositely disposed dogs '80,

and when the machine is at rest the right hand dog 80 held against movement by one arm of a yoke 81 which constitutes part of the escapement device, the said yoke beingr mounted on a pivot 82 and pulled by a sir-lug 83 in a direction to hold the right hand l ork oi? the yoke under the right hand dog. At the last part ol the movement oil the slide bar (37, this yoke Sl is actuated. For this purpose an cvarapemcnt device 's provided, that is to say, the slide bar (37 has a laterally projecting: rigid arm 8st, we Figure (l, which car .cs a pin running in a slot 85 on the end oi a drag; link As soon as this pin a lives at the end of the slot 85 it shifts the yoke 81 to the right and lets the sh it 76 make one halt-revelutiou. .Qlut it will permit only one haltrcvolution because the spring operates (as the bar (37 moves back to its normal position) to pull the yoke back so that its right rand tlfork comes under the approaching dog; 80. In connection with the operation of this part of the mechanism it should be lllltltl'tjltlflll that the movement of the injector arm (33 which occurs simultaneously with the op eration of this mechanism, is su'llicient to enable this arm 63 to travel a slight dis tance beyond the point which it mustreach in order to clear the magazine. rr'llethe arm 63 has completed this movement it is pulled back toward its normal position by a coil spring 87, see Figured, one end of which is attached to a collar on the slide bar (57 and the right head end of whica is attached to the arm 65 on the injector shaft However, before the arm 6;, returns from the slight extra movement or excess moven'ient which is necessary to permit the magazine to have this movement, the magazine will have advanced so that the next pocket {l6 above the played record will be at the level of the arm 68, and hence when the arm 63 completing its return movement by the spring: 87, it will. enter the pocket carrying the next record which is t be played and will push the record through the gap 16 onto the platen 6. While this is occurring the sliding;- pin 32 is held. withc rawn; the movement rt the record onto the platen is therefore unobstructed. hen the record comes onto the pl ten in this way, it will be remenn bored the post 34.- is already latched in an elevated position by means of a small latch; this latch 88, (se Figure 4,) is in the Form of a pawl to engage under a rounded shoulder 89 on the adjacent side oi the post, said pawl being mounted to rock on a vertical pin 90; automatic means is provided to release the latch; in the present embodiment this means is in the term of a curvee arm or tail Ql rigid with the latch and which. is engaged by the incoming record as it arrives at its central position. In other words, as the record comes into place it swings the llll lilil lllll post in its elevated position.

pawl against the action of its spring 92, see Figure 1 and rocks the pawl in a left hand direction. This releases the post 3 1 which is immediately pulled down by its spring 414:. This movement of thepost lets down the guide bar 33 and sets the needle 20 on the upper face of the new record to permit it to be played. Then the post 5 1 drops, the rounded shoulder shoves out the pawl and the side of the post holds the curved tail 9.1 out of contact with the'record. This movement of the post also slides up the center pin 3211c its normal position.

The mechanism above described will opcrate to play all therecords in the 1nagazinc in succession, effecting the automatic changing of each record after it has been played. However, I provide the mechanism with means for stoppingthe playing of a record at any point desired, and when this means is operated the machine automatically effects the changing of the record. In order to accomplish this, I provide a hand operated member which is preferahly in theforni of a stop lever 93, see Figure 6, the outer end of which projects through a slot 94: in the forward wall of the cabinet. The first part of the movement of this lever operates to lift the needle off the record. In order to accomplish this, I pro vide a lever 95, see Figure 11, having its fulcrum at 96 and normally disposed in an inclined p .sition so that it will be forced down by the movement ofthe lever 93 which will be toward the right, as viewed in Figure 11. The outer end of this lever 95 is connected by a link 97 with an arm 98 forming part of a bell. crank lever 99, the other arm 100 of which engages a pin 101 n'ojecting from the lower end of the post 341-. With this organization of parts it will be evident that a movement of the lever 93 toward the right will shove the post 34 upwardly. As; soon as the post is moved upwardly1sufficiently, the spring 92 of the latch 88 will. cause the latch to hold the This movement lifts'the needle oil the record and lowers the pin 32. The further movement of the lever 93 operates a member in the form of a trigger 102, see Figure 11, and this trigger is connected with the needle arm so as to swing the needle arm over to the end of its travel. The construction is such that the lever 93 will operate the trigger 102 and then release it. For this purpose the tr1igg --r 102 is mounted on a pivot 103 one bracket 1041- and the trigger is normally held in a vertical position by a helical spring 105; Above the pivot 103 the trigger has attached to it a link 106 which has a pinand-slot connection 107' with a vertiial arm 108 which extends up from a hori- 11. This rock shaft is supported near the bottom of the cabinet on suitable brackets 110 and its other end is provided with a downwardly projecting inclined arm 111 which is connected to an inclined link 112 which extends upwardly so that its upper end. extends through an opening 113, see I 'gure 5, formed in the aforesaid frame plate 5. The upper end of this link is attached to an arm 11 1 carried on a horizontal rock shaft 115, the other end of said rock shaft having an arm 116 which is connected by a link 117, and spring 118, with the needle arm 19. It will be evident that when the stop lever actuates the trigger 102,

the inclined link 112 will operate to swing the needle arm over to the end of its travel as if it had been moved there through the playing of the record. If the stop lever is immediately returned to its normal position, the operation of the machine will be regular, that is to say, it will automatically effet the changing of the record. I utilize thi same step lever 93 to efi'ect the return or the magazine to its normal position after all the records have been played. This is accomplished by giving the stop lever 93 an extra movement. However, in order to L vent this magazine-returning mechanisu from being brought into action when it is not intended to have it operate, I provide an automatic stop in the path of the lever 93 which prevents this extra movement from occurring, normally. In Figure 11, 119 represents this automatic stop which is in the form of a bell crank lever having a horizontal arm, the end of which is engaged by the lever 93 in the normal operation of the machine. If the record on the platen is the last record to be played, the operator does not return the lever 93 to its normal. position, but holds it lightly against the stop 119. I provide automatic means operating under these circumstances to latchthe injector arm 68 when it is in its extreme right hand position, that is to say, when "it is out of the path of'movement of the magazine; Figure 4; shows this arm 63 but not in the withdrawn position referred to. By latching this arm in its withdrawn position, and withdrawing the automatic stop 119 automatically from the path of the lever 98, the lever 93 may then be given'a further movement which connects the mo tor of the instrument to themagazine to raise the magazine to its normal position. In. order to accomplish this, I provide a latch bar 120, see Figure 10, which is pivotally supported M121, and extends across so that its outer end lies near the path of i but the latch bar is normally held down so that it will not operate as a latch, by a dc tent arm proyecting across 111811131361 edge. This-detent arm 123 is connected by a link .the, path of the end or adjacent the guide 70,

1241 with the stop lever 93. When the stop lever 93 is moved from the position shown in Fig. 11 over against the automatic step 119, the link 124: Will move the detent 123 by rocking it on its pivot 125, and this will permit the spring 122 to pull the latch bar 120 up into the pathof the arm 65. Now, if the stop lever 93 is immediately returned to its normal position, the latch bar 120 will not operate, but if it is held against the automatic stop 119, the automatic mechanism of the machine will operate to remove the record on the platen and as soon as it is removed the bar 120 will swing up into the path of arm this will keep the injector shaft from rotating back, and will latch the injector arm 63 in position to clear the magazine when it moves. in other words, if the stop leveris left in this position, the machine will set itself automatically in readiness to permit the return of the magazine. Furthermore, if the lever, is le in this position, the automatic stop 119 rm 1 be automatically withdrawn to permit i111 necessary extra movement of tee lover to elfect the return of the magazine to its normal position. In order to withdraw the automatic stop, I provide a lever 12?, see Figure 6, one end of which projects into the slide bar 67 and see Figures (3 and Y. The other end 01' this lever 12? is connected to the vertical arm of the stop by a link 128. This will pull the automatic step up out of the path of the lever 93, see Figure 12. The further movement of this lever permitted by the removal oil? the automatic stop closes a clutch 129, see Figure (3, the

movable clutch. member 130 being operated by a link 131 having a slot 132"[0 receive a pinf133 on the lever 93. In the operation of the lever as illustrated in l i 'ure when l U 1 W the pm 133 strikes the .end oi the slot 13",

its further movement will close the clutcln The movable clutch member 1301s sphned on a horizontal shaft 1341 carrying a pinion 135 meshing witha gear wheel 136 carried on the aforesaid shaft 76 which carries the pinion 77. Hence by rotating this shaft 76, the pinion 77 will operate on. the rack 78 to raise the magazine and return itto its normal position.

I provide means for closing the gate 17 when the magazine 15 is being returned in order to prevent any possibility of the edges of the records from getting caught at the lower edge of the wall 15 and in the gap 16. In order to accomplish this, the gate 47 .is connected by a link 137 with a horizontal arm ofa bell crank lever 138, the

vertical arm of which is adapted to be struck by the lever 93, see Figure 12,-when the lever 93 is given this extra movement which may be permitted by the automatic step 119. Figure 12 shows. the automatic azine its feeding movement.

at the end of its travel, of course w ae'm stop raised out of the way so as to permit the lever 93 to pass it when this lever is used to close the clutch 129 and return the magazine to its raised position. In the use of a machine of this type having a magazine it might happen that one or more ol' the pockets 46 of the magazine might be left empty. 1 provide for this contingency and construct the automatic mechanism in such a way that if the magazine has an empty pocket, it will not interfere with the automatic operation of the machine. In other words, if there is an'empty pocket the mechanism will operate to give the magazine another advancing movement so as to bring the next pocket carrying a record, to the level of the platen. In order to accomplish this, I provide means corresponding to each pocket and controlled by the record within the pocket in such a way that it the record is not in the pocket, this means will function to throw the automatic mechanism immediately into operation to give the mag 7 For this purpose I simply provide each pocket with a trip device in the form of a dog 139, see Figures/l and 5. This dog is pivoted at 1 10 and has a small arm or tail 1 1-1 which is engaged by the record 1 12, see Figure l, when the record is in place, so as to extend the spring 143 on the dog. Figure shows the dog held in its inoperative position. However, when the record absent from the pocket, this dog139 is in a projecting position, that is to say, it projects over so that a member such as the pawl 1 H lies in its path of movement. This pawl is pivoted on suitable braciret 1 15 in a prwlzel; or recess 1&6 in the side of the cabinet and when an empty pocket arrives opposite the pawl, the dog 139 corresponding to that pocket projects out over the arm o! pawl 144, so that when the magazine descends, it actuates the pawl. I utilize the movement of this pawl to swing the needle arm 19 in itslinal position, that is to say, to the end of its travel. The arrival of the needle arm Oil-[*3 the automatic mechanism to no late feeding mechanism for the magazine. ln-

cidenl'ally the record-changing nuichanism will go through. the movements oi exchanging the record although the played record will already have been removed from the platen.

In order to enable the pawl 14%.: to actuate the needle arm in the manner described, one arm of the pawl is attached to a link 1.137 which extends downwardly, its lower end being secured to an arm 14S carried by the aforesaid rock shaft 109, see Figures 6 and 7. The direction of movement of the link 147 will be upward so that the rotation ol the rock shalt 109 "ill produce a pull in the link 112, already described.

llii

"started by the spring 24!. action of the cam 38 on the arm 39, the lever The pin-and slot connection, already described, in the link 106, will permit the return of trigger 102 to its vertical position while leaving the needle arm in the position that it may he moved to by the leve r 93 in stopping the playing of a record.

The general mode of operation of the machine will now be briefly described. The record on the platen 6 is played in the ordinary way, that is to say, the needle starts at the outer edge of the record and moves inwardly toward the center. lVhen the needle arm 19 arrives at the end of its travel, the arm 30 pulls on the link 29 and operates the stop device this removes the slide 26 from in front of the arm 31, see Figure 5. As soon as this occurs, the leat spring 2st" exerting its force against the toe of the cam 24 initiates a right-hand rotation of the counter shaft 24. The movement Q en to the shaft by this spring; 24; is suflicient to cause engagement of the teeth oi? the mutihited gear with the roi'ltinuously driven pinion l3. Illhis pinion. 13 rotates the shaft 24- in the same direction in which it was Through the arm 4-1, see Figure 8, shoves up the sliding post 34; whereu 'ionthe latch 88 see Fin". 4-) latches this post in an. elevated position. 'lh is movement raises the bar 33 and through the agency of the linger 35 raises the needle of? the record. Vhile the slidingpost 33 being raised in this way, the sliding pin is beingwithdraw i by actusiting, arm 4;, There is then no obstruction to prevent the removal of the record. which has just been played. This is :u-complished immediately by the cam 58, operating lever and link 53, see Figure 6., which is attached to the arm on. the ejector shaft 51.. This swings the ejector arm 50 around so that it slides the record oil of the platen and into its corresponding pocket 46 where it belongs. As the ejector arm 50 swings around, see Figure 4., the arm 59 through the agency or" the slot (31 and barGO, engaging the post 652, swings the needle arm 19 outwardly to s starting )osition in which it is shown in Figure As the played record moves over into its magazine pocket 4:6, the injector arm 63, see Figure 4, swings out of the pocket into which the record isadvancing; this injector arm is swungbai'ak by means of the pin 66, see Figure 6, operating upon the arm carried by the injector shaft 641. This swings the arm 63 away back out of the path of the magazine 45, that to so it moves be end the curved edge 71 of the magazine, As soon as the incctor arm 63 has moved clear of the magazine, then the arm 84, see Figure 6, actuates the link 86 to rock the escapement yoke 81,

- thereby permitting one half-revolution of the shaft e and ope'fating through the pinion.

77 and rack 78, see Figure 8, to permit the eration of the arm 30 produces all descent of the magazine until the next pocket 46 above, has come into line with the platen; in other words the double dog pawl 79 cooperates with the yoke to effect a single halitrevolution of the shaft 76 so that the escapement yoke 81 holds the magazine in its new feeding position. As soon the magazine has accomplished this leading movement, the injector arm 63 commences its swing toward the left and engages the record 142 in this pocket, and slides it out onto the upper face of the platen. As the record comes over to its proper position the forward edge of the rec; rd engages the pawl 91. of the latching pawl 88, see lligure l, and this releases the sliding post 34: from this latch andlets the needle 20 down onto the record. The movement of this post, of course, operates through the arm 41, and the arr; 4.2 to slide the pin 32 up into the central opening ot th record. The sliding pin then exactly cent, s the record on the platen, and the playing (it the recinid will begin a" once. The above operation constitutes snbstantially one oomph cycle in the normal operation of the machine.

I shall now describe an abnormal opera tion which will. occur it the operator ot the instrument desires to stop the playin a record after it has begun or at any time hetore the playing; ol the record has been completed. In orde to do this the oper n simply moves the lever .3, see ll". (3.

He moves this lever as liar to the rig-it as l A l it will go, see Figure ll, whi will bring the lever up flgillhf-J the automatic st lll which will prevent flil'lllll movement of the lever. As the lever beginsits niovezn" toward the right, see Figure ll, it opera e; the lever 95 and this actuatesand. arm 100 which. raises the post ill; as soon as the sliding post 34 has been lil. it will be automatically l, su'lncicntly, latched in its raised position by the automatic latch 88. This removes the needle treni the record in. the same manner as ocours in the normal operation of the machine. Immediately a'ljter this has occurred, the ,ver 93 strikes the 10:2, see Figure lit, and this actuates the link 106 and rocks the rock shaft 109, thereby producing a pull on the inclined link 112, see Figure 7, and this operates the rock shattllli, see Figure 4- and produces a pull in the link 117 exerted through spring 118; this pulls the needle arm 19 over so as to bring the linger 35 against the right hand step 37 5 in other words lli'lXlOVQS the needle. arm over to the end of its travel. The movement otthe needle arm to this position throng the or automatic movements of the record changing mechanism so that the ejector arm hills then actuated to shove the record otl i the the platen, and into the magazine. It the the link 97 which operates when it is r i 119. will now ha e been automatically withdogs of the double pawl 79 permit lever 98 is then returned to its normal position, 1t rides back over the trigger 102, w1ll be per nitted by the sprlng this return movement of the lever is facilitated b the beveled unoer end of the tri 'e'er 102.
